Many people here are running 2.4 Ghz radios with their electric vehicles. Including me.
It seems this ofna is a pretty big on road car. I think your biggest problem is going to be getting a motor mount.
You may have to e-mail mike (RC-Monster owner) and see if he can make a mount.
You did not specify how much money you were willing to spend. But you could get a NEU 1521 series motor to push that car around. Even a 1515 series would push it around pretty good. There are many people pushing around heavy 13-15 pound all aluminum savage trucks with a 1515 series NEU motor.

A MGM 22418 ESC would be good:
